Lithium-ion batteries typically consist of three parts: lithium-ion cells, a protective circuitry casing, and a rubber case.
Rechargeable lithium batteries typically have a voltage of 4.2 volts when fully charged, though they can also have various voltages. For instance, a power supply current of 1000mA, or 1000mAh, can be used for one hour.
The maximum number of times a lithium battery may be fully charged and used to generate light is its life. Charging techniques include trickle charging, constant current charging, fast charging, and slow charging.
